Internet service provider Sandvine recently released a report that mentioned a very interesting phenomenon: compared with last year's data, encrypted network traffic (SSL) is showing explosive growth this year.

The change is evident in Europe: the share of SSL traffic across Europe during peak periods has quadrupled to 6.1 per cent, compared with 1.47 per cent last year. This rate of growth far exceeds the growth level of the overall flow. (figure below)

In North America, the share of SSL traffic has also increased slightly, nearly doubling from 2.29% last year to 3.8% this year. Although the proportion of SSL traffic is not large, considering that the overall traffic growth is generally only 20% to 40% per year, while SSL traffic has increased several times. (figure below)

The growth of encrypted traffic shows the trend of globalization. Growth in Latin America is even more exaggerated, from 1.8% last year to 10.37% this year.

In China, the number of paid SSL certificates issued by Wotong CA has doubled compared with 2013. In August 2014, free SSL certificate products were upgraded (supporting all browsers and mobile terminals), and the signing volume increased greatly, which was liked by the majority of users. Among them, the number of applications such as e-commerce websites, game websites and IDC websites increased significantly.

The most important reason for the surge in SSL traffic may be attributed to Edward Snowden, the whistleblower of NSA, and the American "prism" surveillance program that he and his friends exposed. Google and several other well-known Internet companies also announced a few months ago that SSL would be the default connection method. More and more operators and users pay attention to network security.

The use of encrypted connections has almost become standard for some large e-commerce, banks, securities and other websites with sensitive data streams as early as a few years ago. Netizens have also learned how to use encrypted links to protect their information in constant network events. All kinds of media are also constantly guiding netizens to pay attention to whether there are "https" secure links when conducting all kinds of transactions.
